Hi all, Im in the process of rebuilding/stroking my 304 to a 355 with a Yellaterra whipple supercharger on top.
I contacted the boys at COME performance regarding the 355 stroker kit which will cost about $2300. I told them that i will be fitting a whipple s/c with just standard boost (about 8-10 psi i think). Im not looking to drag or do 1/4miles just a good street car that ill give a good squirt every now and then.
They told me that the kit would not work for forced induction as they say the crank and pushrods could break and that i would need special lower comp forged pistons too. They said that they do a kit for forced induction but thats $5500(billet crank,Hbeam rods etc).
The kit i was looking to buy was their 355 forged piston stroker kit for $2300 as stated above. It consists of
:Iron crankshaft
robe forged flat top pistons(not sure what the compression ratio will be)
:4340 forged steel "I"beam con rods
:all bearings and piston rings
:ARP studs/bolts
Its out of a VP Calais so only 2bolt main caps
I have read on hear of some guys s/c or turboing stock and mod 5l on reasonable boost and the motors seem to handle it fine. But dont know what type of pistons and what ratio the mod ones are using.
Does anyone know if this 355 stroker kit will be fine for the just street use and a squirt now and then?
I dont mean or intend to rubbish the guys at COME as i do have alot of respect for their work but i feel like they just want the extra $ out of me for something that will never see a drag strip/ 1/4 mile. I mean if guys on here are F/I on mild to high boost on relatively stock 5l with no problems. Then surely the kit im looking to buy should easily handle mild boost?
Thanks in advance
